Forums → Games → GEMCRAFT CHAPTER 0 - How to complete the "blue ribbon" around the level icon?

I am playing Gemcraft Chapter 0. OK, I know I am late...
I see when I win in a battle mode (for instance, Endurance) a little blue square appears in the grey ribbon that exists around the level icon. I completed all available modes including Arcane but there is still two grey squares not converted in blue to complete the whole ribbon. Is there any hidden mode or something I have to do to really complete the blue ribbon?
